Model T Go-Kart Front Axle & King Pin System
Every once in a while someone asks us, “Do you have a front axle system for my Model T Go-Kart?”
For the longest time, the answer was no.
The reason is simple. The front axle is not just another aluminum casting.
Broken Front Axle: Ucellini
These axles take a beating, and the material matters. Some of the original-style replacement axles have been made from aluminum, similar to what was used on the Ucellini karts. Unfortunately, we have seen firsthand what can happen when the material and design are not up to the job.
So we decided to do something about it.
We now offer a high-quality nodular cast iron front axle system.
This is an authentic 1/2-scale Model T Go-Kart front axle, faithfully reproduced from the original design and cast in nodular cast iron.
In layman’s terms, nodular cast iron is tough stuff. It gives us the strength and durability we were looking for in a front axle that is going to see real use on a Model T Go-Kart.
We have also reproduced the front spindles in nodular cast iron. The spindles are true to the original design and provide a direct replacement for worn or stripped-out king-pin threads.
These aren’t just parts that look right. We built them with the intention of making a front-end system that can actually be used.
Made in the USA and hand-crafted with care, these parts are designed for Model T Go-Kart owners who want to restore their kart and have confidence in the front end when they are finished.

Model T Go-Kart Front Axle
Already have your king pins and spindles, but need a strong replacement front axle?
We offer our 1/2-scale Model T Go-Kart front axle separately, allowing you to replace just the axle without purchasing a complete front axle system.
This axle is an authentic reproduction of the original Model T Go-Kart design and is manufactured from nodular cast iron.
Why nodular cast iron?
Because the front axle is one part of the kart where strength really matters. These karts were built to be driven, and the front axle needs to withstand the loads and abuse that come with real-world use.
Our nodular cast iron axle provides a strong, durable alternative to weaker aluminum replacement designs.
Using Our Axle With Your Existing King Pins
Our front axle is designed to work with our king pins and front-end components. However, if you are using the axle with your existing king pins, some adaptation may be required.
Our king pins are intentionally made slightly longer than the original design so they can be fitted to different applications.
If you are purchasing the axle only, you should be aware that you may need to provide a spacer underneath the king pin to make up the difference in height and achieve the proper fit with your existing components.
Every vintage kart can be a little different, so please check your dimensions carefully before ordering.
Built for Restoration — Built to Use
This isn’t a decorative reproduction. We manufacture these parts for people who are actually rebuilding and driving their Model T Go-Karts.
Made in the USA from nodular cast iron and manufactured with the strength and durability needed for a working front end.

Model T Go-Kart Front King Pins
Not everyone needs a complete front axle. Sometimes you already have a good axle and just need to replace worn or damaged front spindles and king pins.
That is why we offer our nodular cast iron front king pins separately.
These king pins are designed specifically to work with our Model T Go-Kart front axle and are manufactured to match it properly. They are made from nodular cast iron for strength and durability and are a great choice when rebuilding or repairing the front end of your Model T Go-Kart.
A Little Extra Length — On Purpose
Our king pins are made slightly longer than the original design. This is intentional.
Because there are several variations of Model T Go-Karts and other similar vintage karts, having a little extra material allows you to fit the king pin to your particular application.
In most cases, you should expect to have the king pin shortened to the required length. We recommend having this done by a qualified machine shop, preferably using an end mill, so the end is cut accurately and cleanly.
Please understand that these king pins are not guaranteed to be the exact finished length required for your particular kart. Some modification may be necessary.
Original McDonough Kingpin on the left is a little shorter than our Kingpin on the right.
These are not a one-size-fits-all bolt-in part. They are a high-quality starting point designed to give you the material and strength needed to properly rebuild your front end.
And while they are designed to work with our front axle, they can also be adapted to other applications. If you’re restoring a Model T Go-Kart or even another vintage kart such as a Stutz Bearcat-style kart, these may give you the replacement part you’ve been looking for.
